"Why is it that this metal is so prevelant here yet gold is nearly non existant?"- J.E
Platinum is a very light coloured metal. It has a very strong shine to it. By it's very nature it has a strong connection to magic and other similar forces.
Enchantability
Platinum is only a little better then iron when it comes to imbuing it with magic.
Rarity and spawning
Platinum is not that rare, it is about as rare as iron but it does not spawn in veins like iron.
